Richard Kevin Sherman (born March 30, 1988) is an American football cornerback for the Seattle Seahawks of the National Football League (NFL). He was drafted by the Seahawks in the fifth round of the 2011 NFL Draft. He played college football for Stanford, both as a wide receiver and as a cornerback.

Since entering the league, Sherman has more interceptions (24) and defended passes (61) than any other NFL player, and many analysts consider him to be the league's best cornerback. Sherman is part of the "Legion of Boom," a nickname given to the Seahawks' starting secondary which contributed to Seattle having the best pass defense in the NFL in 2013. This unit helped the Seahawks win their first Super Bowl in New York in February 2014; their 43-8 win over the Denver Broncos matched the third-largest margin of victory ever in the history of the Super Bowl. In May 2014 Sherman became one of the NFL's highest-paid defensive players after signing a $57.4 million contract extension with $30 million guaranteed with the Seahawks.

Sherman's outspoken personality, tendency for making big plays, and his frequent trash-talk have seen him become one of the NFL's most well-known and divisive players. He garnered national attention with a post-game interview made immediately after his tipped pass ensured the Seahawks a dramatic victory over the San Francisco 49ers in the 2013 NFC Championship game, in which he labeled himself the "best corner in the game" and called San Francisco receiver Michael Crabtree, to whom the decisive pass had been thrown, a "sorry" receiver. In June 2014 it was announced that Sherman would feature on the cover of the Madden NFL 15 video game.
